Problems solved by technology

The problem arising from this type of devices is that they not only work under circumstances of seismic activity, but they function as well under normal loads from traffic, wind or temperature, which provokes wear as well as the need of carrying out continuous maintenance operations, for example, the change/reposition of the oil/silicone, the change of worn out parts, etc.
The problem with this type of devices, besides the fact that once the breakage has taken place the device becomes unusable, being necessary to substitute at least the axial blocking means; consists in that the surface of the breakage of this type of materials is frequ...

Embodiment Construction

[0010]The mechanical protection device provided by the invention solves in a fully satisfactory manner the above explained problems thanks to a very effective new structure which does not need any type of maintenance, being easily adjustable to different effort values according to the specific needs in each case.

[0011]In this connection, the device of the invention starts from a telescopic structure having two arms, one of them displaceable within the other, both having corresponding attachment means with the peculiarity that the arm with a lower cross section, that is, the arm which is displaceable within the arm with a larger cross section, has multiple grooves in a sense perpendicular to the displacement, which grooves in the normal working situation stand opposite to other grooves of the same size arranged in the arm with larger cross section. Both sets of grooves are blocked by a rigid element, preferably a cylinder which, depending on the axial load to which it is submitted, m...

Abstract

The device of the invention consists in a telescopic element with two arms, one of them movable within the other, having in its corresponding ends attachment means (3), so that the shorter arm (2) has means with an axial groove (5) which in the normal working situation is operatively opposite in respect to an axial chamber (6) of the internal portion of the longer arm (1), so that in said chamber a blocking element is movable vertically in respect to the groove, preferably a cylinder (7) opposing the effort of an elastic element located within the corresponding housing (11) which is encased in said groove (5) blocking the device and permitting its unblocking once the effort of the elastic means on the cylinder is exceeded. The device is reusable and it is easily adjustable to different levels of effort for its unblocking.

Description

OBJECT OF THE INVENTION[0001]The invention refers to a device which has been specially designed for its installation in structures of civil works, in parallel to a number of dampers, in order to mitigate the effects produced by seismic vibrations.[0002]The aim of the invention is to provide a mechanical device to permit the actuation of other devices once exceeded a predetermined effort level, which may be easily adjusted, without wear or maintenance problems, having as well a reusable character.BACKGROUND OF THE INVENTION[0003]Within the field of the practical application of the invention that is, civil work structures, various types of dampers are known for seismic engineering, which act as union elements between two structures which must stay without relative movement in the normal work situation but which in front of high efforts produced by seismic effects must permit the displacement between said structures in order to absorb the vibrations with the assistance of a number of d...
